Now You Can Have Dual Cord Dependability

For All Your Critical Systems

If your electronics application is one of the many that requires continuous operation — without tolerance for even scheduled downtime — you need the reliability provided by dual power sources.

Many of today’s servers and other computing systems are equipped with dual power cords…designed to provide built-in redundancy by allowing connection to two separate power sources. In a similar move, facilities are now introducing this level of dual cord reliability to critical equipment that operates on a single power input by supplying two independent electrical feeds. The key to making it all work, however, is to have a dependable switching mechanism to support it.

What Makes A Reliable Switch?

The transfer switch should have proven technology and design features to ensure that it will operate dependably when you need it. The swihching mechanism should be easy to configure, install, use and maintain.

A switch needs to operate swiftly and reliably enough to compensate for “fast” power failures such as UPS system failure, circuit breaker trip or operator error — without affecting operation of the protected equipment.

The Liebert SmartSwitch does exactly this by providing rapid switching between two independent AC power sources, for uninterrupted operation of critical electronic equipment.

Liebert SmartSwitch Enhances The

Availability Of Power To Your Critical

Electronic Equipment

Modeled on proven UPS technology, the Liebert SmartSwitch point-of-use power transfer switch is placed at the most effective spot — the last connection upstream of the protected equipment — allowing dual AC power paths all the way up to the critical load. From design to operation and maintenance, Liebert SmartSwitch has the features that optimize power availability:

Features & Benefits

Flexibility:

■Transfers manually or automatically.

■Allows selection of preferred input source without rewiring or load shutdown.

■Provides integral maintenance bypass to both input sources for servicing convenience.

Higher Availability:

■Switches quickly between two AC power sources, making power transfer time invisible to your protected equipment.

■Allows module replacement without load shutdown, with hot-swap electronics.

■Employs Break-Before-Make switching to eliminate connecting together of the independent power sources, even under faulted conditions.

Lowest Total Cost Of Ownership

■Detects potential switch failures before the problem becomes critical, through diagnostics and transfer tests.
